ROOFING MATERlAYL.

SPECIFICATION forming part of Letters Patent No. 490,668, dated January31, 1893. Application filed January 30, 1892. Serial No. 419,846. (Nospecimens To all whom it may concern:

Beit known that I, GEORGE S. LEE, a citizen of the United States,residing at Hawthorne, in the county of Passaic and State of New Jersey,have invented certain new and useful Improvements in Roofing Materials;and I do hereby declare the following to be a full, clear, and exactdescription of my invention, reference being had to the accompanyingdrawings, which form a part of this specification, for a more full andcomplete description of all parts thereof.

My invention relates to a roofing material.

The object of my invention is to provide a rooting fabric which willwithstand the thermal changes without tearing or separating the fabricat the cenientage, where nails are driven, or at any other anchorage,but can be cheaply and expeditiously laid, made, applied or removed,with but little injury to the main body, if required to be taken upwithin any reasonable time.

To this end my invention consists of a web of canvas, muslin, sheeting,burlap or other textile fabric, covered with successive layers ofdisintegrated paper, rag, or wood pulp, thoroughly intermixed, andincorporated with a compound which will be more fully hereinafterdescribed.

The paper or wood pulp made use and mention of .is derived from a wasteproduct; that of old papers of any and all characters, hackled, torn,andreduced to a pulp, dried, and admixed as before stated.

In the accompanying drawings: Figure 1 indicates a sectional View of myimproved rooting fabric. 1n represents a smooth strip in themanufactured fabric two inches in width, running lengthwise of thematerial and left barren of rock surfacing. Fig. 2 is a perspective viewof a roll of the manufactured roofing, having a surface of granulatedstone, quartz, sand, excepting that portion represented at 1a. Fig. 3 isa perspective view of a roof showing the fabric applied thereto, thesurface being corrugated, or otherwise ornamented, in any desirablemanner, as shown at D. Fig. 4 is a vertical longitudinal section showingthe manner of making the fabric.

Referring to the drawings by letter: A,

Figs. 1 and 2, represents the covering of granulated rock.

B, Fig. 1, represents the successivo layers of pulp incorporated withthe compound, although only one layer may be employed.

C, Figs. 1 and 2, represents the backing of canvas, sheeting or burlap.

1a, Figs. 1 and 2, represents a section of the rooting fabric two inchesin Width, and running lengthwise of the fabric, which in manufacturingis surfaced or covered with airslaked lime to prevent adhesion whenrolled, at points not sanded, and leaving a clean, smooth surface, uponwhich (in the process of application) the overlapping layer of fabriccan be readily cemente/d thereto to form a perfect union between theupper and lower layers, and avoid their being held apart by any foreignsubstances, rock, sand or gravel, as would be the case if the surfacingwere applied to eXtreme outer edges of 'the roofing fabric, and. ifcovering every portion of it. Instead of the employment of air slakedlime, I may simply cover the margin unsurfaced by rock or quartz with atape of paper or fabric.

B, Fig. 1, represents the saturated layers of pulp held together,solidified and incorporated by a composition to any required thickness,and upon which may be compressed a layer of granulated rock, sandor.quartz. The composition employed is composed of asphaltum, with fromfifteen to twenty per cent. of residuum, or dead oils, to which (whenliquefied by heat) is added in a pulverized state thirty-three andone-third per cent. of its total Weight in disintegrated pulp, givinghardness and tenacity to the compound, and great durability in wear, andresistance to the heat of the sun.

The fabric thus formed and described is properly coated on the upper orwearing surface with granulated rock, sand or quartz, crushed andscreened to No. 14 mesh as its coarsest state, and to No. 30 mesh as itsfinest, and embedded into the face of the fabric by compression or othersuitable means. This surface may be embossed, or otherwise finished, bypainting in ornamental designs the exterior surface to produce theeffect of tiles,

shingles or other roofs, as shown in Fig. 3.

In Figa-t 1 designates the vat for contain- IOO ing the asphaltum 2 isthe paper roll from which the paper is fed to the rolls; 3 is a steamtable over which it passes; 4 is the backing; 5 is a tape roll; 6 is thelime distributer; '7 is the hopper forcontaining the granulated rock; 8are the pressure rolls between which the material passes and by which itcompressed; 9 are the drawing rolls, and lO is the winding drum uponwhich the completed fabric is Wound. The operation of these parts willbe readily comprehended from Fig. 4.

Having thus described my invention, what I claim and desire to secure byLetters Patent is:

A roofing material consisting of a sheet of textile material, a layer ofasphaltu m, a backing of burlap or the like, a layer of crush rookembedded in the asphaltum and leaving a barren marginal edge, and anon-adhesive material placed over said barren edge and adapted to beremoved therefrom, substantially as herein described.

In testimony that I claim the foregoing as my invention I have hereuntoset my hand thls 25th day of January, A. D. 1892.
